Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
Answer:
Yes you can. The charging current will be the lowest of the two current ratings of device and charger. The charger and the phone have complex internal circuitry that enable this behaviour.
But using a weaker charger for your phone will only lengthen charging time. And using a stronger charger than that the phone will accept doesn't affect charging at all and only wastes money.
Helium and nitrogen because they are both from the noble gas group.
Answer:
E= 8501.2
Explanation:
Given Data;
Speed = 10.6 km/s = 10.6*10^3 m/s
Magnitude = 0.802 T
The magnitude of the electric field is calculated using the formula;
q E = q v B
E = v B
= 10.6 *10^3 * 0.802
= 8501.2
The direction of the electric field will point along the negative z-axis
